STX1B and depressive symptom measurement: These included solute carrier family 12 member 5 (SLC12A5) (P = 7.13 × 10−10 with depression), TRIO binding protein (TRIOBP) (P = 3.59 × 10−8 with intelligence), STX1B and solute carrier family 25 member 12 (SLC25A12; both of which had a putative effect on neuroticism with P = 1.26 × 10−8 and P = 6.42 × 10−6, respectively).
